i just updated the code so that i can use a "meta-name" as described in dial(2), like:
8.out '$cpu'
but i'm not happy with how dnsresolve()/csresolve() functions turned out.
is there a better way?

it turns out the right thing to do is to just consult cs directly, which can resolve any of 1.2.3.4, google.com, finn (where ndb has a sys=finn line), '$ipgw'.

Ndb's only incurable problem (it may be curable, but it looks hard) is
that it is strictly case sensitive in places, like the ethernet
address, where it would be preferable if it wasn't.
I have yet to find a practical reason to disconnect domain names and
IP addresses, but that could be another stumbling block.
For the rest, I think the design is pretty sound, even remarkable.
Lucio.
